A-Tech 8GB DDR3L 1333 ECC UDIMM 2Rx8 1.35V Dell A5180167 A5180168 A5185929 A5256356 server RAM

Dell-Compatible 8GB DDR3L ECC Module

This 8GB DDR3L 1333 ECC UDIMM replaces Dell part numbers A5180167, A5180168, A5185929 and A5256356 in supported servers and workstations. It adds 8GB of error-correcting memory to systems that require 1.35V unbuffered DIMMs. Buyers whose platforms demand registered DIMMs or a different voltage cannot use this module.

Simple 240-Pin DIMM Installation

The module installs like any standard 240-pin DDR3 DIMM; align the notch, press firmly until the retention clips click, and the system recognises the memory at POST. The most common issue is mixing this unbuffered ECC stick with registered or load-reduced DIMMs, which prevents the server from booting. Verifying the motherboard manual for supported ECC UDIMM populations avoids that mismatch.

Steady 1.35V Operation Under Load

Rated at 1.35V with CL9 latency, the module maintains its DDR3L 1333 speed during sustained workloads without stepping up to the higher 1.5V used by standard DDR3. The low-voltage design reduces heat output when the server runs at high utilisation for extended periods. Systems limited to 1.5V-only memory controllers will not support this DDR3L part.
